The artist I am looking to add work from is Jan Toorop, died in 1928 (https://rkd.nl/nl/explore/artists/record?query=toorop&start=2).
So most (probably almost all) of the works will be safe to upload to Commons. Right statements chosen by institutions do often not represent the correct copyright statement. It is custom to only whitelist domains that contain only PD material? Because I saw some other whitelisted domains that i.m.o also contain copyrighted material. Is it not the responsibility of the uploader to check whether it is safe?
Thanks!
